Drag from NSTableView to Finder / Outside of app?

A.) Perform a Drag and Drop from my NSTableView to the Finder.
B.) Perform a Drag and Drop from another NSTableView to anywhere
outside the app to "poof" that data. (Similar to a sidebar entry in
the Finder).

There seems to be quite a lot of confusion relating to this/these
topic[s], especially in the way it was previously asked in several
mailing lists, so I'm hoping to get a decisive answer from you guys!
